Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

I TRY TO TURN ON THE TV. i GET A FLASHING GREEN,


This symptom seems unusal as there is, what I assume to be, a self check system that monitors conditions and progress of the start up cycle. If there is an abnormal condition recognized during start up, after a short amount of time there should be a malfunction indicated by the LEDs on the front of the set.

Perhaps the self check system is not able to function. If you haven't tried yet, unplug the TV for a few minutes and try it again to see if a reboot of the controls will help. Other than contacting Sony customer service or a local authorized service company, this is the extent of my knowledge about what to try.

There is a error code check that can be displayed, but only if the lamp will come on. To display the error codes, start with the TV off. Using the remote, in sequence press: DISPLAY, 5, VOLUME - (down), POWER. Codes will then be displayed on the screen when the display comes on. To clear the displayed malfunctions, press 8, then press ENTER. To exit the error check mode, turn the TV off by pressing POWER.

Is it the bulb or is it a bigger problem???


i just replaced my 4th bulb in 5 years, some service techs think it might be the ballast, you can get a ballast repair kit for around $50.
personally i think the design of the tv is the problem. i was going thru bulbs about one per year, until i moved my set to another location in the house,away from any draft,doors or windows. the last bulb last almost 3000 hours, the previous bulb last only 1200 hours.
my new bulb was $139. + tax and 20 minutes to install myself, id like to get rid of this TV but you cant sell it for anything maybe when it fails again i will donate it to AMvets

50PZ800U 50" Panasonic Plasma won't keep displaying the source


Seems like the HDMI section of the plasma is damaged. I would call Panasonic and try to get it serviced under waranty since the display is less then a year old. Just make sure you dont mention anything about a storm or power surge. Let them know only if they ask that you are using a surge protector/power conditioner on all your devices.

TV will not turn on


Good Morning Chris,
OK, first of all lets unplug the TV and wait 15 minutes for the High Voltage to discharge.
Remove the back and follow the power cord to the power supply. Somewhere around there you should find a fuse. (there may be more than one) get a bright light to look inside and try to find as many fuses as you can. Remove each fuse one at a time and check them with an ohm meter.
If you don't get a good solid reading on any of them replace the fuse or fuses with the exact same rating. Even if you get a reading and the display is jumping around and will not stablize, replace the fuse. Usually a good fuse taken out of the circuit will display a good steady reading on the meter.
I hope this solves your problem.
Have a great day!

Well, If you see on-screen display and Menu on TV screen that shows problem is with connections wires of DVD Player etc. Also check Cable connector at rear of TV.
One more trick it to unplug TV from AC outlet for couple of minutes and replug back in and power it up. Hope this will fix TV problem.

Blank Screen - Panasonic PT-50LC13-K


Hey Ben, The TV is alerting you it is about time to change your light bulb, it will keep on doing this until the light bulb just dies.
Order your Bulb via On Line at any of the places, there are different prices, but average for the authentic one with the chasis included is @ 260.oo and only takes @ 5 days to get delivered. You can save up to 140.oo if you just order the pure light bulb, and go the extra mile changing it, I just explain someone how to about it, only takes you 30 mins. Good look, I hope I get help for my problem too.
